Part Number 76550-09006-101 is a DC Starter Generator manufactured or catalogued by Sikorsky Aircraft.
In some cases a proprietary airframe or engine manufacturer's part number may be assigned to identify the same unit that
was manufactured by the component OEM. These rotable components generally apply to light turbine powered fixed wing
aircraft and helicopters. Mechanically driven by the engine or APU with a dual purpose, the start function provides
motorized torque to start the engine, then transitions to generator mode generally providing 28 VDC power with a 150-400 Amp
continuous load range. These units are air-cooled and most weigh between 20 to 50 lbs, depending on specific part number.
Most units are produced according to the FAA minimum performance standard specified in FAA TSO-C56a/b. The starter
generator interface with aircraft is usually via QAD kit, to facilitate quick and efficient field replacement. The QAD kit or
'Quick-Attach-Detach' kit generally includes a mounting adapter plate or bell housing, with a matching ring clamp. When starter
generator is removed for aftermarket MRO service, the starter generator only is usually removed - with the QAD mount
remaining attached to the aircraft. The starter generator with QAD kit assembly configuration is usually purchased by the
airframe manufacturer for new production installation before the aircraft enters the aftermarket. All part numbers should
be verified as having qualified FAA approved installation certification and specific make/model eligibility for the intended use.
